Fix 2011/11/11 |
| 3016 |
|
|
| 3017 |
|
@ Optimize for object's size. |
| 3018 |
|
|
| 3019 |
|
I rearranged functions/variables into three groups in order to reduce |
| 3020 |
|
object's filesize. Also, I added kernel config options for reducing more |
| 3021 |
|
by excluding unnecessary functionality. |

| 3025 |
|
@ Fix kernel config mapping error. |
| 3026 |
|
|
| 3027 |
|
Due to a typo in ccs_p2mac definition, mode for CONFIG::file::execute was |
| 3028 |
|
by error used when checking "file getattr" permission. Most users will |
| 3029 |
|
not be affected by this error because CONFIG::file::execute and |
| 3030 |
|
CONFIG::file::getattr are by default configured to use CONFIG::file or |
| 3031 |
|
CONFIG settings. |

Fix 2011/12/13 |
| 3034 |
|
|
| 3035 |
|
@ Follow __d_path() behavior change. (Only 2.6.36 and later) |
| 3036 |
|
|
| 3037 |
|
The behavior of __d_path() has changed in 3.2-rc5. __d_path() now returns |
| 3038 |
|
NULL when the pathname cannot be calculated. You must update to this |
| 3039 |
|
version when using with 3.2-rc5 and later kernels, or the kernel will |
| 3040 |
|
panic because ccs_get_absolute_path() triggers NULL pointer dereference. |
| 3041 |
|
|
| 3042 |
|
The patch that changed the behavior of __d_path() might be backported to |
| 3043 |
|
2.6.36 to 3.1 kernels. You must update to this version if the patch was |
| 3044 |
|
backported, or you will experience the kernel panic as with 3.2-rc5. |
| 3045 |
|
|
| 3046 |
|
The patch that changed the behavior of __d_path() also changed the way of |
| 3047 |
|
handling pathnames under lazy-unmounted directory. Until now, TOMOYO was |
| 3048 |
|
using incomplete pathnames returned by __d_path() when the pathname is |
| 3049 |
|
under lazy-unmounted directory. But from now on, TOMOYO uses different |
| 3050 |
|
pathnames returned by ccs_get_local_path() when the pathname is under |
| 3051 |
|
lazy-unmounted directory (because __d_path() no longer returns it). |
| 3052 |
|
|
| 3053 |
|
Since applications unlikely do lazy unmounts, requesting pathnames under |
| 3054 |
|
lazy-unmounted directory should not happen unless the administrator |
| 3055 |
|
explicitly does lazy unmounts. But pathnames which is defined for such |
| 3056 |
|
conditions in the policy file (if any) will need to be rewritten. |
| 3057 |

Fix 2012/01/20 |
| 3059 |
|
|
| 3060 |
|
@ Follow changes in 3.3-rc1. |
| 3061 |
|
|
| 3062 |
|
Use umode_t rather than mode_t. |
| 3063 |
|
Remove ipv6_addr_copy() usage. |

Fix 2012/02/25 |

|
|
| 3067 |
|
@ Follow changes in linux-next. |
| 3068 |
|
|
| 3069 |
|
UMH_WAIT_PROC constant (currently 1) is scheduled for renumbering in 3.4. |
| 3070 |
|
|
| 3071 |
|
Use UMH_WAIT_PROC constant instead of hardcoded constant in preparation |
| 3072 |
|
for backporting call_usermodehelper() related changes. If renumbering was |
| 3073 |
|
backported, you will start experiencing the kernel panic upon execution |
| 3074 |
|
of external policy loader (i.e. /sbin/ccs-init), for the kernel will no |
| 3075 |
|
longer wait for completion of external policy loader process. |
| 3076 |
|
|
| 3077 |
|
Although I changed to use UMH_WAIT_PROC constant, this change could fail |
| 3078 |
|
to detect renumbering in 2.6.22 and earlier kernels, for UMH_WAIT_PROC |
| 3079 |
|
constant is currently available to only 2.6.23 and later kernels. If you |
| 3080 |
|
started to experience the kernel panic, please check whether renumbering |
| 3081 |
|
was backported or not. |

Fix 2012/02/28 |

|
|
| 3085 |
|
@ Fix mount flags checking order. |
| 3086 |
|
|
| 3087 |
|
Userspace can pass in arbitrary combinations of MS_* flags to mount(). |
| 3088 |
|
|
| 3089 |
|
If both MS_BIND and one of MS_SHARED/MS_PRIVATE/MS_SLAVE/MS_UNBINDABLE |
| 3090 |
|
are passed, device name which should be checked for MS_BIND was not |
| 3091 |
|
checked because MS_SHARED/MS_PRIVATE/MS_SLAVE/MS_UNBINDABLE had higher |
| 3092 |
|
priority than MS_BIND. |
| 3093 |
|
|
| 3094 |
|
If both one of MS_BIND/MS_MOVE and MS_REMOUNT are passed, device name |
| 3095 |
|
which should not be checked for MS_REMOUNT was checked because MS_BIND/ |
| 3096 |
|
MS_MOVE had higher priority than MS_REMOUNT. |
| 3097 |
|
|
| 3098 |
|
Fix these bugs by changing priority to MS_REMOUNT -> MS_BIND -> MS_SHARED |
| 3099 |
|
-> MS_PRIVATE -> MS_SLAVE -> MS_UNBINDABLE -> MS_MOVE as with do_mount() |
| 3100 |
|
does. |
